Anyway to export custom functions to VM?

I searched Wiki and didn't find out how to do it.

It will be a very useful feature.

A vote from me as well. This would be a really big deal for porting LOVE2D-Webplayer to JSREPL.

This is not JSREPL-specific, but emscripted Lua exposes the standard C API. This API is what we used to write the interface between JSREPL and Lua. Although not done in the above code, it's fairly easy to use JS functions inside Lua by implementing a lua_CFunction on the JS side. At one point while experimenting with integration strategies, we even had Lua coroutines yielding to and resuming from JS functions.
